Abstract

The stable xenon/CT method has been expanded to study in addition to the tissue flow the flow of the vessels in the brain. This method was then applied to a series of baboon experiments to measure the flow and diameters of vessels and their dependence on the partial pressure of carbon dioxide (PACO₂). The method uses the value of the flow to distinguish vessels from tissues. The results from an experimental animal study show that (1) the location of the vessels with a diameter larger than 0.3 mm can be detected, (2) the vessel flow follows a Poiseuilles type law, (3) the average of the vessel flow is much higher near the skull at low PaCO₂, whereas at high PaCO₂ the average vessel flow is nearer the center.
